Hi!
I just realized that the previous member
FiniteElement** coefficient_elements
and
std::vector<FiniteElement> finite_elements
, respectively were removed from the UFC class.
The coefficient finite elements are still there.
Yes, but I need the ones which correspond to the test and trial function
spaces.
I need these ones or
more precisely access to the underlying ufc::finite_element.
Can anybody give me a quick hint how to achieve this in the newer DOLFIN
versions? I already scanned through the code, but could not find a
simple solution.
From a FunctionSpace, you can extract a dolfin::FiniteElement, followed
by a ufc::finite_element.
But not from within the UFC class since the dolfin::Form form member is
private. Since the UFC class takes a dolfin::Form argument in the
constructor and a reference to the Form is stored in the UFC class,
would it not be meanful to make it accessible by having a
const Form& form() const;
member function in the UFC class?
Just pass the Form and don't use UFC.
The UFC class is just a convenience class for assembly, and shouldn't
generally be used. The less that is in UFC, the easy things are to
maintain (as I know from having made some recent changes).
Ok, I can changed that in my code, it was just convenient since I also
need the UFCcell. To be honest, the code dependencies between UFC,
ufc::form and dolfin::Form are sometimes a bit hard to follow and the
overall reasoning/big picture behind the implementation is difficult to
grasp for me :), so many thanks for the quick help!!
